Troubleshooting & FAQ
Q: How do I confirm this fits my engine?
A: This impeller is specifically for Suzuki 2-Stroke 9.9HP (DT9.9) and 16HP (DT16) models from 1980–1982. Please compare your engine model and year against the "Compatible Engine Models" table and verify that your existing part number matches 17461-93501 or 17461-93500.
